Nickel Chrome Alloy Ni80cr20 Ni70cr30 Ni60cr15 Ni35cr20 Heating Elements Spiral Wire Resistance Nichrome Strip


Cr20Ni80 has excellent comprehensive properties. High-quality heating elements will choose Cr20Ni80. Cr20Ni80 has the advantages of good oxygen resistance, high strength, non-magnetic, high emissivity, good corrosion resistance, no softening, no deformation, and low permanent elongation.
Nickel-chromium, nickel, ferrochrome alloy wire with electric high temperature oxidation resistance, high strength, not soften and a series of advantages. When used in a long time, the same type and the permanent elongation is very small, which is more Cr10Ni90 alloy with excellent comprehensive properties, is to produce high-quality varieties of choice for electric components.
